FASTENING DEVICE.

Application led May 29, 1916.

To all whom t may concern Be it known that I, JOHN A. ANDERSON, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Fastening Devices, of which the following is a specification.

My invention consists of an improved flastening device which is especially serviceable as a window or door lock, but it may be used advantageously for other purposes.

One object of my invention is to produce a fastening device including a bolt which may be manually moved into an operative position by a single movement thereof in one direction and automatically locked in said operative position.

Another object is to so construct my invention that the bolt will be automatically moved from its operative position when one of the members is moved into a certain position.

A further object is to so make a device having the above noted features that it will be durable, efficient, and can be assembled quickly and manufactured at a small cost.

These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which- Figure 1 is a face view of my invention. Fig. 2 is a section on the line a-a of Fig. 1, showing the bolt in an operative position. Fig. 3 is a view of similar nature to Fig. 2, showing the positions occupied by certain of the elements when the bolt is in an inoperative position, and Fig. 4 is a perspective view of a locking plate which I employ.

Referring to the drawing, a casing 1 provides a cylindrical chamber 2 having one end closed by a portion 3 of the casing, and the other end closed by a plate 4 which is secured to the casing 1 as shown at 5, and eX- tends beyond the casing 1 as clearly shown in Figs. 2 and 3.

A cover 6 lits the plate 4, and has a recess providing a chamber 7. The cover 6 includes flanges 8 having screw holes 9. The plate 4 has a projection 10 provided with an elongated opening 11 forming a slide-way for an oE-set tenon 1121 on a slidable locking plate 12 which is located within the chamber 7.

A bolt 13 has an enlarged cylindrical por- Specication of Letters Patent.

tion 14 located between its ends, and this portion 14 fits and slides within the chamber 2, and provides shoulders 15 and 16. One end of the bolt is designed to slide through an opening or hole 17 in the portion 3 of the casing 1, and the opposite end of the bolt is designed to slide through openings 18 and 19 in the plate 4 and cover 6 respectively under certain conditions during the operation of my invention. The latter end of the bolt has a threaded opening 2O into which screws the threaded end of a stem 21, the latter having a push button 22 on its opposite end and located outside of the cover 6.

The olf-set tenon 11a is so disposed as to extend substantially midway between the inner surfaces of the plate 4 and cover 6, and provides room for a spiral expansion spring 23, the latter having one end bearing against the projection 10, and its other end bearing against the shoulder 24 provided by said offset tenon, so that said spring tends to move the locking plate 12 in the direction of the arrow shown in Fig. 2.

The end 25 of the locking plate 12 has a handle 26 screwed therein, said handle projecting through a slot 27 in the cover 6, and a lug 28 projects from the inner surface of the cover and forms a guide to prevent the locking plate 12 from lateral movement adjacent the end 25, it being noted that the tenon 11a is confined within the slide-way 11, and prevents any lateral movement of the opposite end of the plate 12, so that a smooth and even movement of said latter plate is attained.

The stem 21 is of smaller diameter than the bolt 13, and thus provides a shoulder 29 which, when the plate 12 is moved into the position shown in Fig. 2, will abut the plate 12. The stem 21 extends through a slot 30 which is narrower than the opening 18. If the locking plate 12 is moved by 'means of the handle 26 into the position shown in Fig. 3, so as to bring the opening 28 directly in alinement with the bolt 13, a spiral expansion spring 31 which surrounds the opposite end of the bolt and engages the shoulder 15 and the end portion 3 of the casing 1, will move the bolt longitudinally through the openings 18 and 21, and withdraw the operative end 32 from the socket 33 which may be made of any construction providing a recess for said end 32 of the bolt. It is obvious, however, that this socket 33 may be attached to one sash of a window,

While the cover 6 and casing 1 may be attached to the other sash of the Window, the bolt acting to lock both of said sashes. In some instances, however, the socket 33 may be dispensed With and a hole sufficiently large to receive the end 32 of the bolt may be formed directly in the member which it is desired to lock to the member carrying the cover 6 and casing 1.

vWith my improved fastening device .it vvill be noted that a single pushing movement against the button 22 will compress the spring 31 and move the bolt into the position shown in Fig. 2, and as soon as the opposite end of the bolt has passed entirely through the opening 18, the spring 23 Will expand and automatically move the locking plate into the position shown in Fig. 2, a portion of said locking plate extending across the end of the bolt 13, so that when the button 2,2 is released, the bolt will still remain in an operative position, the slotted portion 30 extending around the stem 21. To release the bolt it is merely necessary to move the locking plate by means of the handle 26 into the position shown in F ig. 3 until the opening 1S is directly in line with the bolt 13 when the spring 31 by expanding Will move the end 32 of the bolt into an inoperative position, this movement being limited by the shoulder 16 coming in contact With the plate 4 as shown in Fig. 3. The handle :26 is preferably screwed into the plate as illustrated and may be removed if it is desired to separate the several parts.

In assembling and attaching my invention, a hole may be drilled into the sashes to accommodate the casing 1 and the socket 33, and screvvs may be inserted through the openings 9 to secure both the plate 4 and the cover 6 to the outer surface of the sash. As illustrated, the casing 1 has its extensions 5 riveted to the plate 4 and the cover 6 has its inner edgestapered, so that when placed over the plate 4, and the screws inserted within the openings 9, the plate 4 cannot be dislodged.

yl/*lille I have described my invention as taking a particular form, it Will be understood that the various parts of my invention may be changed Without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come Within the scope of the appended claims, said claims `being intended to cover such equivalents as the prior art does not reveal.
